# 5e — Production integrations of OpenAI image models for software-asset generation

## Executive summary

OpenAI's image-generation endpoints (`dall-e-2`, `dall-e-3`, `gpt-image-1`, `gpt-image-1-mini`, `gpt-image-1.5`) are now plumbed through every major AI-application framework and no-code platform. For a product that enhances prompts and returns brand assets, the useful integration layers fall into four buckets:

1. **Framework SDKs** — Vercel AI SDK (`openai.image('gpt-image-1')`), LangChain (`DallEAPIWrapper` + `OpenAIDALLEImageGenerationTool`), and LlamaIndex (`OpenAIImageGenerationToolSpec`). Each gives the model a standard tool/agent surface, but none currently expose the full `gpt-image-1` parameter set (background, input fidelity, mask) — most wrappers still speak the DALL·E 3 dialect.
2. **iPaaS / no-code** — Zapier (AI Image Generator template), Make.com (OpenAI module), n8n (native `OpenAI` node with `gpt-image-1` support since PR #14870). These are the cheapest path to production for non-developer users and all share the same pattern: OpenAI call → persist to blob storage (Drive/S3/R2) → webhook downstream.
3. **Design/creative platforms** — Figma community plugins (FigPilot.ai, Summon.AI, the official `figma/ai-plugin-template`), Canva Magic Studio (runs on `gpt-image-1-mini` per OpenAI's 2024 case study), and Shopify apps built on Gadget.dev. These are the distribution channels where a prompt-to-asset skill earns its keep — they already have the users, they need the quality.
4. **Hosting + MCP wrappers** — Replicate (`openai/gpt-image-1`, `openai/gpt-image-1-mini`, `openai/gpt-image-1.5`) for webhook-based async, Modal / Baseten for custom wrappers, and a growing field of MCP servers (`openai-gpt-image-mcp-server`, `mcp-server-gpt-image`, `lpenguin/openai-image-mcp`) that expose the Images API to Claude Desktop, Cursor, Codex, and any MCP-speaking agent.

**Key production constraints** (all models): organization ID verification is mandatory before keys can call `gpt-image-1`; Tier-1 accounts get only **5 IPM** (images/min), Tier-5 gets 250 IPM; typical end-to-end latency at `quality=high` / 1024×1024 is **8–15 s**, with tail latency up to ~2 min on complex prompts; images from the raw OpenAI endpoint **expire within ~1–2 hours** so every integration needs to copy bytes to persistent storage immediately.

## Integration catalog

### Framework SDKs

| SDK | Package / entry | Models supported | Notable quirk |
|---|---|---|---|
| Vercel AI SDK | `@ai-sdk/openai` → `openai.image('gpt-image-1')` + `experimental_generateImage` / `generateImage` from `ai` | `dall-e-2`, `dall-e-3`, `gpt-image-1`, `gpt-image-1-mini`, `gpt-image-1.5` | `response_format` is **not** sent for `gpt-image-1` (PR #5938, merged 2025-04-23); model only returns b64 JSON. Sizes capped to `1024x1024 | 1536x1024 | 1024x1536`. |
| LangChain (Python) | `langchain_community.utilities.DallEAPIWrapper`, `OpenAIDALLEImageGenerationTool` | Defaults to `dall-e-2`; `model_name` param accepts `dall-e-3` or `gpt-image-1`, but size/quality validators lag the model — override via `model_kwargs`. | Returns a URL by default; the agent tool returns the raw string, so you must persist before the URL expires. |
| LangChain (JS) | `@langchain/community/tools/dalle` | DALL·E 2/3 only as of Apr 2026 | No first-class `gpt-image-1` tool yet; community issues open. |
| LlamaIndex | `llama-index-tools-openai-image-generation` (`OpenAIImageGenerationToolSpec`) v0.6.0 | DALL·E 2/3; gpt-image-1 requires passing `model="gpt-image-1"` and overriding size/quality enum. | `to_tool_list()` wraps to a `FunctionAgent` tool; exposes `image_generation` and `load_data` tool calls. |
| OpenAI Agents SDK | `openai.agents` + `ImageGenerationTool()` | `gpt-image-1`, `gpt-image-1.5`, `gpt-image-1-mini` | Native: emits `image_generation_call` item in responses, handles multi-turn edits and masks without hand-rolling tool JSON. |

### iPaaS / low-code

| Platform | Module | gpt-image-1 support |
|---|---|---|
| Zapier | AI Image Generator template / OpenAI "Generate Image" action | Yes; template persists output to Google Drive / Airtable because OpenAI URLs expire. |
| Make.com | OpenAI app → "Create an Image" module | Yes (selectable model, quality, size, format); pair with HTTP+Google Drive for persistence. |
| n8n | Built-in OpenAI node, operation "Generate Image" | `gpt-image-1` added in PR #14870 (2025). Exposes quality, resolution, output format, compression, background, input fidelity, mask. |
| Pipedream | OpenAI action "Create an Image" | Yes, via direct REST. |
| Retool | OpenAI connector / REST resource | Yes, via REST with base64 → S3 write step. |

### Design-platform integrations

| Product | Integration shape | Notes |
|---|---|---|
| Figma — `figma/ai-plugin-template` | Official template plugin, Next.js + OpenAI chat + image | Reference for streaming + secure `clientStorage` key storage. |
| Figma — FigPilot.ai | Community plugin, ChatGPT + DALL·E-3 in-canvas | Closed source; UX benchmark. |
| Figma — Summon.AI (`alex-streza/summon-ai`) | Open-source TypeScript plugin, DALL·E 2 image-gen + variants | Uses `create-figma-plugin`, turborepo; good skeleton to fork and upgrade to `gpt-image-1`. |
| Figma — DALL-E Bro | Community plugin with built-in prompt library | Stores API key in `figma.clientStorage`. |
| Canva Magic Studio | Internal product powered by `gpt-image-1-mini` per OpenAI case study ("Canva: 5B uses of Magic Studio", openai.com/index/canva) | External integration via Canva Connect APIs (REST) + Apps SDK; OAuth+PKCE, webhook async jobs, template+data pipelines. |
| Shopify | Custom apps via Gadget.dev or direct Admin API; no official OpenAI-bundled module | Real-world deployments (Aura & Co. / Photta case study) report ~85% cost reduction vs studio shoots, ~30 s turnaround vs 14 days, +31% conversion. |

### Hosted inference + async wrappers

| Host | Route | Reason to use |
|---|---|---|
| Replicate | `openai/gpt-image-1`, `openai/gpt-image-1-mini`, `openai/gpt-image-1.5` | One API key covers many image models; **built-in webhook delivery** via `webhook` + `webhook_events_filter: ["completed"]`; billing passthrough requires a verified OpenAI key linked to the Replicate account. Outputs expire at 1h — save immediately. |
| Modal | Custom `@app.function(image=Image.debian_slim().pip_install("openai"))` wrapping `client.images.generate()` | Good for burst/concurrency control, spot capacity, and adding pre/post-processing (rembg, upscaling) in the same container. |
| Baseten (Truss) | Deploy a `Truss` whose `model.py` proxies to `gpt-image-1` plus local post-processing (background removal, vectorization) | Gives an **OpenAI-compatible endpoint** in your own VPC, useful for enterprise SLAs. |
| Cloudflare Workers AI / Vercel Functions | Direct REST to OpenAI with edge retry + KV caching | Low-ops; handle the 1–2 min tail latency with a background queue (Upstash QStash, Trigger.dev). |

## SDK reference patterns

### 1. Vercel AI SDK — `gpt-image-1`

```ts
import { experimental_generateImage as generateImage } from "ai";
import { openai } from "@ai-sdk/openai";

const { images, providerMetadata, warnings } = await generateImage({
  model: openai.image("gpt-image-1"),
  prompt: "Flat vector app icon for a note-taking app, rounded square, " +
          "off-white paper with a single blue pencil, no text, clean shadow",
  n: 4,
  size: "1024x1024",
  providerOptions: {
    openai: {
      quality: "high",
      background: "transparent",
      output_format: "png",
    },
  },
});

for (const [i, img] of images.entries()) {
  await Bun.write(`icon_${i}.png`, img.uint8Array);
}
```

Notes:

- Do **not** set `response_format`; the SDK strips it for `gpt-image-1` because the endpoint rejects that param (vercel/ai PR #5938).
- `providerOptions.openai` is how you thread through `quality`, `background`, `moderation`, `output_format`, `output_compression`, and (for edits) `mask` / `input_fidelity`.
- Use `ai-gateway` if you need multi-provider fallback (e.g. OpenAI → Gemini Flash Image on outages).

### 2. LangChain (Python) — tool-using agent

```python
from langchain_community.tools.openai_dalle_image_generation import (
    OpenAIDALLEImageGenerationTool,
)
from langchain_community.utilities.dalle_image_generator import DallEAPIWrapper
from langchain_openai import ChatOpenAI
from langgraph.prebuilt import create_react_agent

api_wrapper = DallEAPIWrapper(
    model="gpt-image-1",
    size="1024x1024",
    quality="high",
    n=1,
)
dalle_tool = OpenAIDALLEImageGenerationTool(api_wrapper=api_wrapper)

llm = ChatOpenAI(model="gpt-4.1")
agent = create_react_agent(llm, tools=[dalle_tool])

result = agent.invoke(
    {"messages": [("user",
        "Design a transparent PNG logo mark for a Rust CLI called 'ember'")]},
)
```

Gotchas: `DallEAPIWrapper.run()` returns a URL for DALL·E but may return base64 for `gpt-image-1` depending on community version — wrap in a persistence step. LangGraph's `create_react_agent` is the blessed upgrade path from the deprecated `initialize_agent` helper.

### 3. LlamaIndex — function agent with image tool

```python
import os
from llama_index.tools.openai import OpenAIImageGenerationToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

image_tool = OpenAIImageGenerationToolSpec(
    api_key=os.environ["OPENAI_API_KEY"],
)

agent = FunctionAgent(
    tools=image_tool.to_tool_list(),
    llm=OpenAI(model="gpt-4.1"),
)

response = await agent.run(
    "Generate a 1024x1024 transparent PWA icon for a meditation app."
)
```

### 4. Replicate async + webhook (Node)

```ts
import Replicate from "replicate";
const replicate = new Replicate({ auth: process.env.REPLICATE_API_TOKEN });

const prediction = await replicate.predictions.create({
  model: "openai/gpt-image-1",
  input: {
    prompt: "Isometric illustration of a notebook and pencil, pastel palette",
    quality: "high",
    size: "1024x1024",
    background: "transparent",
  },
  webhook: `${process.env.PUBLIC_URL}/api/replicate/webhook`,
  webhook_events_filter: ["completed"],
});
return Response.json({ id: prediction.id });
```

The webhook fires once with `status === "succeeded"`; download `output[0]` to R2/S3 within the hour before Replicate deletes it. For <15 s predictions you can skip the webhook and poll `replicate.predictions.get(id)` every second.

### 5. Modal wrapper (Python) with queue + retries

```python
import base64, io, modal

image = (modal.Image.debian_slim()
         .pip_install("openai>=1.40.0", "tenacity"))
app = modal.App("gpt-image-1-proxy", image=image)

@app.function(
    secrets=[modal.Secret.from_name("openai-secret")],
    timeout=180,                # tolerate tail latency
    retries=modal.Retries(max_retries=3, backoff_coefficient=2.0),
    concurrency_limit=50,       # stay inside Tier-4 IPM
)
def generate(prompt: str, quality: str = "high") -> bytes:
    from openai import OpenAI
    client = OpenAI()
    r = client.images.generate(
        model="gpt-image-1",
        prompt=prompt,
        size="1024x1024",
        quality=quality,
        background="transparent",
        output_format="png",
        n=1,
    )
    return base64.b64decode(r.data[0].b64_json)
```

Concurrency-limit + retries is the cleanest way to honour OpenAI's IPM ceiling from a serverless layer; Modal's queue auto-holds callers when the limit is hit instead of bubbling 429s.

## Scaling / cost notes

### Pricing (Apr 2026, direct OpenAI)

| Model | 1024² low | 1024² medium | 1024² high | Max long edge |
|---|---|---|---|---|
| `gpt-image-1` | $0.011 | $0.042 | $0.167 | 1536 |
| `gpt-image-1-mini` | ~$0.005 | ~$0.018 | ~$0.07 | 1536 |
| `gpt-image-1.5` | $0.009 | $0.034 | $0.133 | 1536 |
| `dall-e-3` | $0.040 (standard) / $0.080 (HD) | — | — | 1792 |
| `dall-e-2` | $0.016 (1024²) | — | — | 1024 |

> **Updated 2026-04-21:** The `gpt-image-1.5` "Max long edge" column previously listed 2048 — this was incorrect. Official API docs confirm the same three sizes as gpt-image-1: `1024×1024`, `1536×1024`, `1024×1536`, max long edge 1536 px. Pricing figures above updated to match official OpenAI pricing page (Apr 2026): low $0.009, medium $0.034, high $0.133 per 1024² image.

Token-based billing backs the GPT-Image pricing: ~1K output tokens for a 1024² low → ~4.5K for high; add prompt tokens (cheap) and input-image tokens for edit mode.

### Rate limits (OpenAI usage tiers)

| Tier | Spend threshold | IPM (gpt-image-1 / -mini) | Notional $/min @ high 1024² |
|---|---|---|---|
| Free | — | not supported | — |
| Tier 1 | $5 lifetime | 5 | ~$0.84/min |
| Tier 2 | $50 lifetime + 7d | 20 | ~$3.34/min |
| Tier 3 | $100 + 7d | 50 | ~$8.35/min |
| Tier 4 | $250 + 14d | 150 | ~$25/min |
| Tier 5 | $1,000 + 30d | 250 | ~$42/min |

A prompt-to-asset product should assume **Tier 3–4 capacity** for first-party quota (50–150 IPM) and route overflow to Replicate/Azure OpenAI as a soft fallback. Rate-limit handling needs:

- Exponential backoff with jitter (`tenacity.wait_random_exponential(min=1, max=60)` + `stop_after_attempt(6)`), which OpenAI's own cookbook recommends.
- 429-aware queueing (Modal `concurrency_limit`, Sidekiq throttled-worker, BullMQ `Queue.add` with `rateLimit`).
- A per-tenant bucket if you multi-tenant the key — otherwise one noisy customer will throttle everyone.

### Latency profile

- **Median**: 8–15 s for `gpt-image-1` at `quality=high` 1024².
- **Tail** (p95–p99): 30–120 s under load or on compositional prompts.
- **gpt-image-1.5** claims up to **4×** speedup per OpenAI's Nov 2025 launch.
- Replicate adds 0.5–3 s overhead + cold-start if no warm deployment.
- Canva's published infra note: tens of thousands of A100/H100 GPUs behind Magic Studio, K8s-elastic — this is the bar for "interactive" latency at scale; for smaller products, assume the user will wait >10 s per image and design the UI around it (optimistic previews, skeletons, email/push delivery for slow jobs).

### Persistence & hygiene

- **Image URLs from OpenAI expire**; `gpt-image-1` only returns `b64_json`, so save bytes to blob storage (S3/R2/GCS) immediately with a content hash filename.
- **Strip EXIF / embed C2PA**: OpenAI images carry C2PA metadata; keep it if you want provenance, but some CDNs strip it — set `Content-Disposition` explicitly.
- **Moderation failures** are a first-class outcome. `gpt-image-1` returns `error.code = "moderation_blocked"` with no image. Plan fallback copy ("We couldn't generate this — try reframing the request") and surface `moderation` level tuning (`low` vs `auto`) to enterprise tenants.
- **Organization verification** is blocking: Tier-1 keys without verification get 400s on `gpt-image-1`. Document this in the onboarding checklist.

## Agent / MCP exposures

MCP is becoming the cross-agent "USB-C" for image tools. If our prompt-to-asset ships a skill, it should register a matching MCP server so Claude Desktop, Cursor, Codex CLI, and custom agents can call it natively.

Community MCPs already in the wild:

- **`openai-gpt-image-mcp-server`** (npm, v1.2.4, Jan 2026) — supports `gpt-image-1` and `gpt-image-1.5`, multi-image batches, history, metadata embedding. Install: `npm i -g openai-gpt-image-mcp-server`, then register under `mcpServers` in `~/Library/Application Support/Claude/claude_desktop_config.json` with `OPENAI_API_KEY`.
- **`pavelsukhachev/mcp-server-gpt-image`** (v1.2.0) — dual Images API (`gpt-image-1`) + Responses API (`gpt-4o`), SSE streaming, caching, stdio **and** HTTP transports. Good reference for a hybrid skill that wants to do both generation and conversational edits.
- **`lpenguin/openai-image-mcp`** — `npx @lpenguin/openai-image-mcp`, covers `gpt-image-1`, `-mini`, DALL·E 2/3; zero-install for VS Code Chat and Cursor.
- **`michaeljabbour/imagen-mcp`** — multi-provider MCP (Gemini 2.5 Flash Image + `gpt-image-1`) with router logic; useful pattern for vendor abstraction inside a single server.

OpenAI's own agent stack:

- **OpenAI Agents SDK** ships an `ImageGenerationTool()` that emits an `image_generation_call` item in the Responses API, complete with `partial_image` streaming events for progressive display.
- **ChatGPT Desktop** image-gen is the de facto end-user UX benchmark; any MCP skill we build should at least match: streamable previews, explicit `background=transparent`, `size` chips, and a "generate 4 variants" affordance.

Design principle for our MCP: expose a **single `generate_asset` tool** with semantic parameters (`asset_type: logo|icon|illustration|favicon|og_image|splash`, `brand` hints, `constraints`) instead of a thin passthrough to `client.images.generate`. The prompt-to-asset is the value-add — the raw Images API is already well-wrapped.
